APERTURA DE PROPOSICIONES Y PROPUESTA DE ADJUDICACIÓN

Lower Gears Engine RPM Limit

The engine will accelerate at a slower rate when this limit is exceeded under normal driving conditions. This is to encourage the driver to shift to the next highest gear. This parameter should remain at the factory default value when using an Automatic or Autoshift transmission, with the exception of the Eaton Top 2.

Lower Gears Turn Off Speed

Vehicle Speed where “Lower Gears Engine RPM Limit” is shut off. This must be matched with “Lower Gears Engine RPM Limit” to the specific drive train for best performance.This parameter should remain at the factory default value when using an Automatic or Autoshift transmission, with the exception of the Eaton Top 2.

Intermediate Gears Engine RPM Limit

Similar to “Lower Gears Engine RPM Limit”. The engine will accelerate at a slower rate when this limit is exceeded under normal driving conditions. Typically programmed to slightly higher rpm than the Lower Gears Engine RPM Limit. This parameter should remain at the factory default value when using an Automatic or Autoshift

transmission, with the exception of the Eaton Top 2.

Intermediate Gears Turn Off Speed

Similar to “Lower Gears Turn Off Speed”. Typically programmed to a slightly higher vehicle speed than Low Gears Turn Off Speed. This parameter should remain at the factory default value when using an Automatic or Autoshift transmission, with the exception of the Eaton Top 2.

Gear Down Protection RPM Limit

Engine RPM Limit when vehicle speed is above “Gear Down Protection Turn On Speed. This is a “hard” limit. The ECM will not allow fuel to the engine above this limit. This is to encourage the driver to shift into overdrive or top gear. This parameter should remain at the factory default value when using an Automatic or Autoshift transmission, with the exception of the Eaton Top 2.

Gear Down Protection Turn On Speed

Vehicle Speed where “Gear Down Protection RPM Limit” is ON. This must be matched to the specific drive train for best performance. Above this vehicle speed limit the engine rpm will be limited by the Gear Down Protection RPM Limit.

Top Engine Limit (TEL)

Maximum engine rpm when the engine is under load. This parameter no longer provide a selectable range. The TEL rpm is fixed at 2120 rpm.

*Excludes special ratings that offer 2150 Top Engine Limit.

Top Engine Limit with Droop

This parameter no longer provides the droop option. No is the fixed parameter value.

Low Idle Engine RPM

Minimum engine rpm.

Transmission Style

Indicates to the ECM the type of transmission configuration installed in the vehicle. It is used by the ECM to determine how to read inputs (brake switch #2, clutch, and neutral switches).

If an automatic transmission is installed, this parameter should be programmed to Automatic Option 1, Automatic Option 2, Automatic Option 3, or Automatic Option 4.

The Manual selection requires a clutch pedal position switch connected to ECM Connector J1/P1, terminal 24. The transmission selections with a neutral switch require a transmission neutral switch connected to ECM Connector J1/P1, terminal-62 (Input #12).The transmission selections with two brake switches require a second brake switch connected to ECM Connector J1/P1 terminal-64 (Input #13). Refer to “ Transmission Style Parameter Switch Input Table” on page 86 for additional information.

The Eaton Top 2 transmission is a manual transmission and requires a clutch switch. The ECM operates two outputs to control shifting between the top two gears of an Eaton Top 2 transmission. A total of four parameters must be programmed for the system to operate correctly.

Eaton Top 2

Eaton Top 2 Override with Cruise Switch

If this parameter is programmed to YES the Cruise Control On/Off switch can be used to disable Top 2 mode. Turning the Cruise Control On/Off switch to the OFF position when the transmission is not in Top 2 mode will disable Top 2 mode (manual operation only). Turning the Cruise Control On/Off Switch to the ON position will enable the Top 2 mode and allow for automatic shifting in the Top 2 gears. When operating in one of the Top 2 gears and Top 2 mode is enabled, switching the Cruise Control On/Off switch to the OFF position will place the transmission in Hold mode (will not shift out of currently selected gear). Returning the switch to the ON position will return to Top 2 mode. Depressing the Clutch while in Hold mode will result in Manual mode (Top 2 disabled).

Top Gear Ratio

Identifies the highest gear ratio for an Eaton Top 2 Transmission. For example, 10th gear for an Eaton Super 10 Top 2 transmission is the Top Gear. Programmable range is 0.000 to 3.750 in 0.001 increments. Default is 0.000. Refer to “Eaton Top 2 Transmission Gear Ratios Table” on page 131 for programmable values for each Eaton Top 2 transmission.

Note: This parameter must be precisely programmed to three decimal places to ensure proper operation of the

Eaton Top 2 and Caterpillar engine drivetrain in the top two gears.

Top Gear Minus One Ratio

Identifies the next to highest gear ratio for an Eaton Top 2 Transmission. For example, 9th gear for an Eaton Super 10 Top 2 transmission is Top Gear Minus One. Programmable range is 0.000 to 3.750 in 0.001 increments. Default is 0.000. Refer to “Eaton Top 2 Transmission Gear Ratios Table” on page 131 for programmable values for each Eaton Top 2 transmission.

Note: This parameter must be precisely programmed to three decimal places to ensure proper operation of the

Eaton Top 2 and Caterpillar engine drivetrain in the top two gears.

Top Gear Minus Two Ratio

Identifies the second to highest gear ratio for an Eaton Top 2 Transmission. For example, 8th gear for an Eaton Super 10 Top 2 transmission is Top Gear Minus Two. Programmable range is 0.000 to 3.750 in 0.001 increments. Default is 0.000. Refer to “Eaton Top 2 Transmission Gear Ratios Table” on page 131 for programmable values for each Eaton Top 2 transmission.

Note: This parameter must be precisely programmed to three decimal places to ensure proper operation of the

Eaton Top 2 and Caterpillar engine drivetrain in the top two gears.
